ELECTRIC WATER PURIFIER AND FILTER.

Seria1 No. 643,214.

Beit known that I, Ana HENRY VAN Pour, a citizen of the United States,and resident of Los Angeles, in the county of Los Angeles and State ofCali'tornia, have invented certain new and useful Improve ments inElectric Water Purifiers and Filters, of which the following is aspecification.

My invention pertains to water purifiers, and it has special referenceto purification by electrolysis.

My object is to provide a small, portable apparatus, which may bereadily attached to an electric socket, and. which has, also,

a filter connected therewith, so that the" operation of purifying andfiltering may be accomplished in a single apparatus.

The invention comprises a pair of tubular electrodes provided with ahead, which carries the electric-terminals, and has the water supplyinlet, and a base which is hollow, and contains a reticulated plate overwhich the filtering paper of material is placed, and below thereticulated plate is a discharge outlet for the water. The base is somade that it may be readily removed from the tubular electrodes, andalso separated so that the interior may be cleansed and new filteringmaterial supplied, all of which will now be set forth in detail.

In the drawing, l ignre 1, is a central, vertical section of thepurifying apparatus. Fig. 2 isa'horizontal section on line 2 2 ofFig. 1. Fig. 3 is a top view of the cap, and Fig. 1 is a horizontalsection on line Hot Fig". 1.

In constructing my invention I provide an inner and an outer tube 5, (3,respectively, of aluminium, the inner tube 5,being secured to adownwardly-projecting boss 7, which is integral with the cap 8, and theupper end of the outer tube 6 is secured to an annular channel inthccap, and held by means of screws 9, or in any other suitable manner.A water inlet 10 is' provided at one side through this cap, and I alsoprovide a pair of binding posts 11, 12, the threaded stems 13 of whichgo into the cap and contact with the ends of the respective electrodes5,

6. The lower end of the inner electrode Patented Mar. 12, 1912.

5, is preferably closed, as shown, and the entire electrode issupported, as shown by the boss 7. The lower end of the outer electrodeis threaded, so that it may be" screwed intothc base member 1 1, asshown at 15. This base member 14 has on its lower side an annular flange16, and below this flange is a reticulated disk 17, over which is laidfilter paper, 18, or other suitable t tering material. A ring 19 of thesame diameter as the flange 17, is placed in the base of the metal shell20, and below the reticulated plate 17, so that when the shell 21 isscrewed up the plate and filter material are held between the flange 17,and ring 19. The shell 20 and edge of the base member 14, are threaded,as at- 21, so as to hold the plate and filter material in place. It willthus be seen that two chambers are formed in the base, the upperchamber22 being designed to receive the electrolyticallyt'r eatcd water throughthe port 23, as it is discharged from the electrical ehambely and thelower chamber 24:, which receives the purified and filtered water, andthe water thus treated is discharged through the pipe manner, and wateris permitted to 'flow intothe inlet pipe 10,.and after treatment itescapes from the electrode chamber to the compartment 22, through theport-23, and passes thence through the filter body 18, to the lowerchamber 524, and discharge pipe 25. For cleaning the filter the shell 20is removed, and for cleaning the electrodes the base member 1 1. isunscrewed. In case of renewals the electrodes may be detached from thecap at the upper end.

What I claim as new, is

In a combined electrolytic purifier and filter, a pair of electrodes,:3. filtering chamber below the electrodes, comprising a base chamber.Signed at Los Angeles, in the county of Inember adjustnbly secnred tothe lower end Los Angeles, and State of 051 of one of the electrodes, ashell surroundin 24th day ofMa A. D1911. said base member, andremovably' attachec to said base member, a filter within the said ADAHENRY VAN Tx ifornia, this I E'chamber, and an inlet and outlet for saidWitnesses:
